I'm also seeing this slightly different violation:

My code is currently calling MediaMetadata.Builder().setArtworkUri() with URIs corresponding to a ContentProvider that provides 1024x1024 AVIF images. I don't think it's practical for me to use smaller images on my end, since my activity actually makes use of the full resolution.
This just started after my phone applied a system update for build number BP3A.250905.014, so I suspect it was caused by a framework change -- I didn't see any violations using whichever build of Android 16 that I was on before.
I haven't spent much time looking at the framework code yet, but I wonder if this from https://android.googlesource.com/platform/frameworks/base/+/master/core/res/res/values/config.xml is related:
<!-- The maximum bitmap size that can be written to a MediaMetadata object. This value
is the max width/height allowed in dips.-->
<dimen name="config_mediaMetadataBitmapMaxSize">320dp</dimen>Media
