Hi Anupam,
Indeed the colour of the display has changed. I am wondering whether Yamaha did this because now the screen will be more readable and less strenuous to the eyes, or simply because the new screen is less onerous.
Or maybe simply the screen maker is producing a new type of LCD screen and all makers of entry level keyboard like Yamaha and Casio are switching to the new screen type.
As for the styles themselves, I liked the two you mentioned. Also Epic Diva Ballad looks great for playing some of Adele’s songs.
Jeremy made another video with the ten new grooves (or DJ patterns), I will be posting it now.
Best Regards,
Vinciane.
