Prores4444 export is YUVA instead of YUV color space

Question

I really have no clue what is going on here. We have a large exterior display we build for. We've done a number of files for it, exported as prores 4444 and all has been fine. We have an outside contractor producing something for us. He exported from AE to prores 4444 and his file didn't run.

After a lot of poking around we saw that it was in YUVA color space, not YUV like the working files. Lots of testing and we're still having that issue, and now, when I export from my AE I'm now exporting into YUVA color space. This makes no sense to me and I can't see anywhere to make a change that will affect that color space. More than that I can't find online references for YUVA anywhere.

The only other difference i can see on inspecting the files is that the new YUVA renders are "Writing Library: Apple" where the working files were "Writing Library: adb0"

So I'm assuming that is an Adobe vs Apple thing, but again, for the life of me i can't see anywhere to change this. Anyone have any ideas?

hiRGBA seems to be equivalant to YUVAthe A at the end means ALPHA, from my investigation.I'm sure you already know this, but in case this is of any use to you. Prores 4444 is adding an alpha channel from my understanding. so yuv would mean no alpha channel and yuva means alpha channel. Did you in some way have some setting, somewhere, for alpha, turned off, which made the export no longer yuva but instead yuv? interpret footage maybe?
