That depends. Something like HDR should be able to fall back to non-HDR since it largely just adds data, so if the format specifies that extra information is ignored, there's a chance it works fine.
I see, but the animation feature cant be compatiable no?
Likely, you'll see the first frame only on older software. Encoding animation in a dedicated animation chunk and using the base spec for the first keyframe sounds like the sane thing to do, so they likely did that.
I'm not going to look into it now, because I would then have to implement it. :D
Haha dont worry, just curious. Your answer is good!
