If buyers of any goods and services are happy with the outcome and consider it money well spent, the happiness they derive is a just reward for their expenditure, and that goes for audio equipment just as much as any other equipment. I recently noted that a Mullard OC81 used but tested 'white jacketed' transistor sold for £41.00 on an auction site. I don't know what the 'white jacket' signifies, but it clearly meant something to the bidders. Unquote
The white sleeving is used to match the silicon heat transfer grease inside the case, as per the photos.
