ISTR that x265 profiles are not yet supported, however you can still
make a MAIN10 file by setting other parameters. for example:-

-c:v libx265 -pix_fmt yuv420p10le \
-preset fast \
-x265-params level=5.2:vbv-bufsize=60000:vbv-maxrate=60000:crf=20

Prodcued some thing that when probed shows:-

Stream #0:0(und): Video: hevc (Main 10) (hev1 / 0x31766568),
yuv420p10le(tv), 3840x2160.....
