no. the reason is that the manufacturer of the LCD did not allow the user to read the data. I do not understand why they do not simply add a command to read out the data.
Anyway, when you can not read the memory, you can not read a byte, alter a bit, and write the byte back. setting a pixel would require this.
A workaround is to use the processor memory as a buffer and work on that. But it is a waste of memory. For a smaller display that might not be a problem. 128x32 for example requires 4096 bits = 512 bytes. 512 is still a lot of sram IMO.
