I will give you a medal if it is actually a SPFD5408.
Please run the LCD_ID_readreg.ino sketch from the MCUFRIEND_kbv library.
It should say 54 08 for a genuine SPFD5408 e.g.
reg(0x0000) 54 08 ID: ILI9320, ILI9325, ILI9335, ...
As far as I know, UTFT does not support any of the Mcufriend Uno Shields.
MCUFRIEND_kbv supports about 40 different controllers.
