Cannot get HDR to work on ProsperoLight

Bug Symptoms

4k 120 hz pyrowave HDR 4:4:4 not working on the ps5 using prosperolight. Says PyroWave HDR10 rejected: enable HDR on the host capture display. Remote monitor shows as hdr off in diplay settings on windows. Turning HDR on via that does not resolve the issue. Prosperolight requests HDR and Vibepollo is set to do HDR when asked by client. Prosperolight dev says it is a vibepollo issue.
