This is not happend with 16bit EXR or Tiff rendering, but Tiff and EXR is more than 3 times bigger filezise.
Try Cineform instead.

My Workflow for HDR 2020 space: After Effects CS6(PC) (.mlv native bit rate 10,12 etc.) Cdng-> 16bitiff (32bit float) with ACR .
On MacPro import the Tiffs's to Compressor , render out to Real Apple ProRes 4444XQ This should be enough .
ACES is a waste of time with canon dslr's  , if you are having problems with clipping in the bottom end you need to get a colorimeters spider and calibrate you  monitor.
Just because it may be a 4k HDR TV doesn't mean it's calibrated correctly to Rec.2020 , even if you have BMD I/0 device .
For HD I use AJA Kona I/0  to Asus LED ProArt 10bit HDMI monitor in sRGB color space
(Asus has a pre-calibrated sRGB setting to 97% of sRGB color space) and with that I still check the calibration every time I grade video .
My 2 cents worth

I think the hole point with ACES is to match color from different cameras without much effort.

It´s all about gamut. Eye perception. Aces is supposed to be doing this better than other spaces. Why else would we use it?

I think you're both right

ACES is a waste of time with canon dslr's 

I don't agree, it could be used as effectively with canon DSLRs as with any other camera, but I have been using MLV App with sRGB forever, and been 90% happy with the results.
