Perhaps things have changed, but when I was still following GOT (I watched until season 4), most nudity were cut when aired here in Taiwan.
In fact there are plenty of complains about this online. There’s even news articles about this back in 2015.
The news article specifically wrote that it was HBO Asia in Singapore that cut those scenes out, and refused to comment why they didn’t just blur the screen instead.
I know they made changes because I watched both versions and was shocked by HBO Asia cutting scenes filled with dialogue that are important to the plot simply because the characters weren’t fully clothed. For GOT it was very confusing.
