Why are my nipples still asymmetric after bottoming out repair? (Photos)

The different could be evened out by a simple skin resection on the left side to make the nipple to fold distance on the left match the nipple to fold distance on the right. I would recommend seeing a board-certified plastic surgeon with extensive aesthetic breast surgery experience.

Nipple position after implant revision surgery
Displacement of Implants: Over time, the implants may shift in any direction causing the need for a revision. In rare cases, a “bottoming out” effect occurs, in which, the implant sinks too low in the chest wall causing the nipple to appear to point upward or be position too high. Generally speaking, if the implant is larger (i.e. heavier) and if a bra is not used regularly during wake time hours there is a greater change toward displacement.

Stretch occurs: when the breast tissue itself stretches between the nipple and fold increasing this distance Though uncommon, this complication can occur from poor implant placement, skin laxity, weight loss, or breastfeeding. During a breast revision, your plastic surgeon restores the natural breast crease and adjusts the implant into a more natural position. It may be possible to do this internally again. but it also may require an inframmamry incision or periareolar incision to decrease the nipple to fold distance

Probably your nipple is in the correct place, but your breast has bottomed out some which makes the nipple look too high.
