I have been wondering about this for quite some time. Some planes will say what type of plane it is on the fuselage, and others will not.
Is there a specific reason as to why some airlines do say what type of plane it is, and others do not?
Some BA 777s have the "Boeing 777" identification and some do not.

Qantas places the type-identification near the wing:

It also seems to be standard that airlines that do place the type-identification will include the variant if they have more than one variant, but JAL and Thai do not do that:

(Note: AF does place the type-identification on their 773ERs, but it is at the front and includes "-300ER")

Placing the type-identification marks certainly varies by airline and aircraft, but is there a "general rule of thumb" that applies to this?
Sorry for any headaches.
