Exporting HDR timelapse sequence out of Lightroom Classic as 16bit TIFF and making a master ProRes 422 HQ HDR video from it. It doesn't work. Please describe in details the settings.

I have tried several different settings from Lightroom and AME but nothing is working.  The videos turn out dull and not accurate.  The exported TIFF are accurate to what is showing on the Lightroom Classic Develop settings.

I have tried the following settings and combinations with no luck:

HDR Graphics White (Nits): Based on Source, 100, 203 and 300

Export Color Space: Rec. 2100 HLG and 2100 PQ

Depth: 16-bpc

Maximum Render Quality (Checked)

It isn’t the exported TIFF files because I got it work using DaVinci Resolve with no issue.  This is a Adobe Media Encoder issue.
