See the above. Partially lit disks look spherical with some editing.
And spheres look spherical without any editing. What's your point?
My point is that short term space flight doesn't prove anything about anything.
But when photographs from those altitudes agree with the expected curvature of the Globe that "short term space flight" might provide a lot of evidence.
Now we have no photographs from North Korean ballistic launches, but many have reached more than enough altitude for that.
Here are a few recent ones:
2017 | | North Korea test-fired a Hwasong-12[31] missile from a test site in the area of Kusong (May 13, 2017). The missile, later revealed to be an intermediate range ballistic missile, traveled 30 minutes, reached an altitude of more than 2,111.5 km, and flew a horizontal distance of 789 km (489 miles), before falling into the Sea of Japan. Such a missile would have a range of at least 4,000, reaching Guam, to 6,000 km.

2017 | | North Korea tested its first intercontinental ballistic missile (ICBM) named Hwasong-14 on July 4. It launched from the Panghyon Aircraft Factory 8 km southeast of Panghyon Airport. It was aimed straight up at a lofted trajectory and reached more than 2,500 km into space. It landed 37 minutes later, more than 930 km from its launch site, into Japan's exclusive economic zone.

| 2017 | | North Korea launched a ballistic missile on September 15 from Sunan airfield. It reached a height of 770 km and flew a distance of 3,700 km for 17 minutes over Hokkaido before landing in the Pacific. |
All these examples are for is to show that rockets/missiles are certainly launched high enough to observe and compare curvature.
There are numerous photos available from other launches taken from all sorts of altitudes up to hundreds of kilometres.
But, when presented, anything that seems to suggest anything but a flat earth is deemed a fake or CGI, so there's not much point presenting more.
