It's rare for large corporations to deny a complete report. But Nintendo did it today. The Japanese corporate entity issued a press release denying that Bloomberg's apparent revelation that Nintendo was encouraging developers to create 4K resolution games for the Switch Pro handheld, which could be canceled, was completely false.
The report by Nintendo falsely states that Nintendo supplies tools for game development on a Nintendo Switch with 4K Support. It insists that this is not true and that there are no plans to make any other Nintendo Switches than the OLED model.
There is always the possibility that Bloomberg's report could technically be accurate that there was a 4K Switch developer kit and that Nintendo did push developers for 4K content. However, Nintendo is trying to claim that the whole report is false.
Bloomberg seems to be standing behind its report, which is not surprising. This report comes from respected journalists in the game/tech industry who are well-sourced in past. It cites anonymous employees of 11 different gaming companies that claim they have a 4K Switch design kit. The publication added a line about Nintendo's denial following Nintendo's tweet.
I would not believe a Nintendo statement that leaves any room for error. This is especially true when the company is under investor pressure to launch its OLED handheld well.
Update at 8:56 PM ET: Bloomberg has updated its post to reflect Nintendo's denial.
