From the perspective of a frequent buyer myself, I would prefer it being opened (but save all the stickers on shrink wrap) so I could have the seller verify that the disc does not suffer from any laser rot that would guarantee a return on my part.
Also, it’s to a seller’s advantage as well to open it to verify the same thing as to ensure no unscrupulous buyer might be trying to con you on a defect you know should not exist. For example, maybe a buyer is trying to replace a rotted disc of the same title and taking advantage of the fact you have no idea if your disc is rotted or not.
So yes... open it and enjoy it
. It won’t affect the value any differently and this particular title is valued anyway by collectors.
