Thanks for looking into it. I will file a feedback as you requested. Regarding the xcode viewer and reality compose they display the texture just fine. Even macOS preview does. It‘s just in a custom app using model IO (about as basic as possible) the texture colors are saturated. Thanks again.

I'm still seeing this with my app targeting 14.2. I have the semaphore in place as well to prevent stalling when getting the current drawable. I noticed in Instruments that sometimes my present command is failing with a message of "Cannot go direct to display due to display rejected". Any ideas what is going on?

I do see it on MTKView, however it seems to behave oddly. If I have my MTKView colorPixelFormat to the default 'bgra8Unorm` (which should render to the drawable in linear color space) but set 'colorspace' to 'CGColorSpace.sRGB' the output is the same as if is 'nil'. I expected it to engamma my MTKView's output for compositing.
