I never found it to be true.
I owned a Samsung S7, it was atrocious, people said it was great, the bloatware was painful, the gesture to open the apps drawer was conflicted with the gesture to open Samsung pay (which didn't worked with my bank), you can't disable Samsung pay, if you switch the launcher, it's still there. Searching the settings took literally 10 seconds. It's default behavior is to stay on while charging, the whole screen have the lock screen burned in now.
My mom own a Samsung 10e, people also said "Samsung software isn't ad now", they rewrote their own clock app. It doesn't support having multiple timers?!? Worse, asking Google assistant to add a timer, reset the previous one. This is due to Samsung bloatware, the stock android clock doesn't have this issue.
