Most converted DV MEL disc titles don’t play in Dolby Vision on M4 iPad Pro (some do on iPhone 17)

Hello,

I’m seeing inconsistent Dolby Vision playback behaviour in Infuse with Profile 8.1 files converted from 4K Blu-ray remuxes. The source discs fall into two categories:

  • HDR10 discs into which I injected a Dolby Vision RPU (some CMv2.9, some CMv4.0) from the WEB-DL streaming version to create Profile 8.1

  • Dolby Vision Profile 7 MEL (CMv2.9) discs that I converted to Profile 8.1 and two for which I injected CMv4.0 levels taken from the WEB-DL streaming version

All my WEB-DL DV titles (Profile 8, mostly CMv2.9) work perfectly on both devices, so I’m trying to determine what distinguishes the disc-derived P8.1 files that fail.

I have used DoVi_Scripts v3.0.8 for all conversions and injections, and I have carefully followed the tutorials and guidance from @The_HDR_Dissector (aka R3S3t9999). Below is a concise breakdown of which converted Dolby Vision titles work and which fallback to HDR10 across my two devices.

On iPhone 17

  • WEB Streaming P8 (CMv2.9):
    :white_check_mark: DV Works: Example A

  • WEB Streaming P8 (CMv4.0):
    :white_check_mark: DV Works: Example B

  • P7 MEL → P8 (CMv2.9):
    :white_check_mark: DV Works: Example D, Example I
    :cross_mark: HDR10 fallback: Example E

  • HDR10 + injected RPU (CMv2.9) → P8:
    :white_check_mark: DV Works: Example C
    :cross_mark: HDR10 fallback: Example F

  • HDR10 + injected RPU (CMv4.0) → P8:
    :white_check_mark: DV Works: Example H

  • P7 MEL (CMv2.9) + injected CMv4.0 levels → P8:
    :white_check_mark: DV Works: Example G

On M4 iPad Pro

  • WEB Streaming P8 (CMv2.9):
    :white_check_mark: DV Works: Example A

  • WEB Streaming P8 (CMv4.0):
    :white_check_mark: DV Works: Example B

  • P7 MEL → P8 (CMv2.9):
    :white_check_mark: DV Works: Example I
    :cross_mark: HDR10 fallback: Example D, Example E

  • HDR10 + injected RPU (CMv2.9) → P8:
    :cross_mark: HDR10 fallback: Example C, Example F

  • HDR10 + injected RPU (CMv4.0) → P8:
    :white_check_mark: DV Works: Example H

  • P7 MEL (CMv2.9) + injected CMv4.0 levels → P8:
    :white_check_mark: DV Works: Example G

Possible factors I’m considering include bitrate, mastering nit values (1000 vs 4000), RPU structure, or differences between Apple’s DV pipeline on iPhone vs iPad.

About the Dolby Vision toggle during playback:
Infuse shows the DV badge on the title page for any Profile 5 or Profile 8 file on both devices.
During playback, however, the Dolby Vision toggle in the gear menu only appears for some titles.

I’m not certain this toggle reliably indicates DV activation. I’m only treating it as a hint because:

  • Profile 5 titles also do not show the toggle, yet clearly play in DV (no colour issues), which makes sense because P5 has no HDR10 fallback path.

  • Profile 8 does have HDR10 fallback, so when the toggle disappears on P8 titles, I suspect HDR10 is being used—but I cannot confirm this 100%.

Even with that uncertainty, the pattern across devices is consistent enough that I’m trying to understand the underlying cause.

Devices & Software version

  • iPad Pro M4 (iPadOS 26.1)
  • iPhone 17 (iOS 26.1)
  • Infuse Pro (8.3.1)

Below are the categories of titles with MediaInfo and DoVi RPU metadata.

What I’m hoping to understand

  1. Whether the DV toggle during playback correctly reflects DV status for Profile 8.

  2. Why WEB-DL Profile 8 titles (CMv2.9 or CMv4.0) consistently work across my devices, while many disc-derived P8.1 titles do not.

  3. Why the iPhone 17 accepts some disc P8.1 titles in DV while the iPad Pro M4 rejects more.

  4. Whether bitrate, mastering levels, or RPU characteristics inherited from P7 MEL might trigger DV fallback.

  5. Whether iPadOS handles Profile 8.1 BL+RPU more strictly than iOS, affecting Infuse behaviour.

  6. Whether there is a reliable conversion method for disc Dolby Vision → Profile 8.1 that Infuse and Apple devices will consistently accept.

Thank you kindly for your time.

I noticed the same behavior on the AVP with some disc rips in DV 8.1.
Toggle is there on the apple TV but not on AVP.

I also noticed that the only titles that refuse to play Dolby Vision (or at least show the toggle) on the iPhone 17 are the ones mastered in Dolby Vision CMv4.0 but delivered in CMv2.9. They’re the only files in my sample with that combination, which might be a helpful lead to investigate.

4

What exactly is this ‘DV toggle during playback’ you refer to. I’m not sure I have ever seen this.

6

While the Dolby Vision movie/show is playing, open the gear icon (the same menu where you choose audio tracks and subtitles). Go to Advanced, then scroll all the way down, you should see a Dolby Vision toggle, which should ideally be enabled.

If the content is Dolby Vision Profile 5, the toggle won’t appear because there’s no HDR10 fallback option.

If you’re watching Dolby Vision Profile 8.1 content but the toggle still doesn’t show up, that usually means the device isn’t playing it in Dolby Vision and is falling back to HDR10 instead.
