Does HLS support MVHEVC HDR10 ?

I am setting up a HLS server for MVHEVC files...

just find that if tag mp4 files using Asset Writer with

let colorPropertySettings = [

AVVideoColorPrimariesKey: AVVideoColorPrimaries_ITU_R_709_2, AVVideoYCbCrMatrixKey: AVVideoTransferFunction_ITU_R_709_2, AVVideoTransferFunctionKey: AVVideoYCbCrMatrix_ITU_R_709_2

]

the HLS playback well on Safari.

but if tag mp4 files using using Asset Writer with

let colorPropertySettings = [

AVVideoColorPrimariesKey: AVVideoColorPrimaries_ITU_R_2020, AVVideoYCbCrMatrixKey: AVVideoYCbCrMatrix_ITU_R_2020, AVVideoTransferFunctionKey: AVVideoTransferFunction_SMPTE_ST_2084_PQ

]

the HLS can not play on Safari.

looks like HLS does NOT support MVHEVC HDR10.

OR

have I lost any setting for MVHEVC HDR10?

thanks.
