I think I heard that in Sweden that ALL sailplanes are required to have
"high visibility" wing tips, nose and tail. I know that several imports
from Sweden did come with such markings.

You might check with the manufacturer about how they meet the Sweden
requirements

Quite a long time ago, the BGA did some controlled tests re visibility
markings. I can't remember the details, but I am fairly certain that the
findings were that conspicuity patches etc did nothing to improve seeing
gliders in the air.

I seem to remember that to be any use the patches must be big and a
single colour - small patches and/or multicoloured ones are quite good
camouflage.
