How the 4K derivative is created, demo with an example

Step 1: extract the color profile

convert -quiet /tmp/ba-obj-5044-8001-mas.tif /tmp/ba-obj-5044-8001-mas.icc

Step 2: create the 4k sized derivative

convert -quiet -profile /tmp/ba-obj-5044-8001-mas.icc /tmp/ba-obj-5044-8001-mas.tif[0] -strip -units PixelsPerInch -depth 8 +matte -resize 3840 -matte /tmp/ba-obj-5044-8001-mas.jpg

Step 3: add the original color profile back

convert -quiet -profile /tmp/ba-obj-5044-8001-mas.icc /tmp/ba-obj-5044-8001-mas-final.jpg
