No, there is no indication of any excess heat, discoloration, or any other damage. If one is concerned about excess heat from the 55W/60 H4 bulb, all he has to do is drill a couple of ventilation holes in the rear cover of the headlight. All the headlights on my other motorcycles are completely open in the back. Only the bulb is covered with a rubber boot.

There is nothing inside the back cover of the headlight that is vulnerable to dirt or rain. The low front fender and the high, well protected location of the headlight will also protect it from the elements. One could drill several ventilation holes in the lower portion of the cover if he were worried about rain entering the headlight.
