HDR10+ backwards to HDR10

[SlashX]

Hello,
I have a question: If I'm using those settings to encode my HDR10+ video, will the video be able to play as HDR10 on device that support only HDR10 and not HDR10+ and also if it will play on device as HDR10+ that ar certified as HDR10+.

x265 --preset slower --log-level 2 --input - --output-depth 10 --y4m --profile main10   --no-hme --rskip 1 --temporal-mvp --weightp --crf 18.00 --qpfile GENERATED_QP_FILE --limit-refs 1 --signhide --range limited --colorprim bt2020 --transfer smpte2084 --colormatrix bt2020nc --master-display "G(13250,34500)B(7500,3000)R(34000,16000)WP(15635,16450)L(10000000,50)" --hdr10 --hdr10-opt --dhdr10-info "E:\Other\Proiect\Windows APP\FastFlix\metadata2.json" --dhdr10-opt --output OUTPUTFILE

I don't have a device that can play HDR10 or HDR10+, I want o buy one, but I want to know if with those commands will allow me to play play the video on compatible HDR10 device.

Thank you!
