Dolby Vision on ffmpeg7.1 has someting changed?

[mr44er]

ffmpeg 2:7.1-6
svt-av1-psy-git 2.3.0.B.r0.gec65071b-1
ab-av1 0.9.1-1
dovi_tool-git 2.2.0.r6.gc59b3cf-1
vulkan-radeon 1:24.3.4-1

I noticed a strange behaviour with DOVI on ffmpeg7. Is this expected or now correct on ffmpeg7, because I don't own DOVI-capable hardware to check? With ffmpeg6 side data didn't change.

Source file:
Side data: DOVI configuration record: version: 1.0, profile: 8, level: 6, rpu flag: 1, el flag: 0, bl flag: 1, compatibility id: 1

Output with ffmpeg7:
Side data: Content Light Level Metadata, MaxCLL=203, MaxFALL=194 Mastering Display Metadata, has_primaries:1 has_luminance:1 r(0.7080,0.2920) g(0.1700,0.7970) b(0.1310 0.0460) wp(0.3127, 0.3290) min_luminance=0.000100, max_luminance=1000.000000

Workflow as usual without crop:
ffmpeg -i source.mkv -c:v copy -bsf:v hevc_mp4toannexb -f hevc - | ./dovi_tool -m 2 extract-rpu - -o RPUnocropxto8.bin
or with crop:
ffmpeg -i source.mkv -c:v copy -bsf:v hevc_mp4toannexb -f hevc - | ./dovi_tool -c -m 2 extract-rpu - -o RPUcroppedxto8.bin
Also no difference with experimental mkv-feature:
dovi_tool -c -m 2 extract-rpu source.mkv

For the encode: --svt dolby-vision-rpu=RPUnocropxto8.bin / --svt dolby-vision-rpu=RPUcroppedxto8.bin

The new part was using libplacebo and as said, ffmpeg7.

After reading https://ayosec.github.io/ffmpeg-filters-docs/7.1/Filters/Video/libplacebo.html out of curiosity I tried test-encodes without libplacebo and with apply_dolbyvision:false, made no difference.
