You can give it a try using this config which is OCIO v2 and works fine in Nuke/Fusion/Davinci Resolve and many other popular renderers.

Affinity requires this file to be called 'config.ocio' in order to be correctly detected and used, please try renaming your config file, restarting the app and trying again

Unfortunately, this is still not working. Also odd that the OCIO v1 config with any naming convention works fine. Please try the supplied OCIO v2 config rename it to config try it and compare it to the same output the OCIO v1 config gives from my previous post. They do not match when using ACES sRGB, the OCIO v2 config is outputting a purely sRGB output without the ACES ODT, aka Un-tone-mapped mode. I have also attached the EXR for your tests. It is working perfectly fine in Nuke/AE etc.

As my previous example shows, the darker "contrasty" output is the correct output, but this is only working in OCIO v1 not the OCIO v2 config. This leads me to think that the built-in OCIO v2 transform for ACES SDR sRGB is not working correctly in the Affinity OCIO v2 implementation, as the other log spaces using the built-in functions are fine. Specifically this function `ACES-OUTPUT - ACES2065-1_to_CIE-XYZ-D65 - SDR-VIDEO_1.0`

Thanks!

Thanks for verifying that for me and I'm sorry to hear this - I can confirm our team have been able to replicate this issue internally and we're getting it logged with our dev team now.

I hope this helps
