Slight livery issues on ANA, JAL's 787, Peach's A320, and FDA's E175 (Reposted)

I found some interesting information regarding the missing red circle and registration number on the wing.

According to Jan’s post in the Transavia B738 livery issues topic, it seems that for the 737-800 (maybe all 737NG series) adding the registration on the wing is not possible due to technical limitations.

For the red tip on A359, it’s because all the A359 wings share the same texture file (except some recent ones), and adding the red tip would affect the entire fleet. To properly do so, the devs have to split the files and that causes more mess.
The A35K used different files for wing textures from the beginning to avoid such inconveniences.

According to his post regarding the red tip on the A359, all the A359 wings share the same texture file.

Since the 737NG series, A320ceo family, and 787 family are not the latest models, it is likely that they also share the same texture file across all the wings, which is why adding a specific registration to the wing is impossible.

However, the E-Jets are much newer models, and some of them already have the registration number on the wing. Therefore, I believe the FDA E175 might have simply been overlooked.
