"nodata_val = chunk" cannot be put into the "chunk := self.raw.read()"
assignment expression combined with a test. At least, I don't see how.
If that's the only 'break' in the loop, then you know that 'chunk' will
have an 'empty' value after the loop, so you can change it to:
while True:
chunk = self.raw.read()
if chunk in empty_values:
break
...
nodata_val = chunk
which then leads to:
while (chunk := self.raw.read()) not in empty_values:
...
nodata_val = chunk
