Newspapermen have their biases. If you called the TV news with a report of someone getting up out of a wheelchair or raising the dead, and you got a modernist, they'd probably dismiss the claim without researching it. If they researched it and corroborated it, would they air it? The head correspondent for Time in Beijing previously (who I think passed away) gave a speech at a university about Jesus in China, and when he went to Hong Kong, he was able to corroborate testimony of healings from multiple parties involved. There was a story about a policeman who imprisoned Christians. I believe he was one of the ones who was healed and became a Christian. As refugees came into Hong Kong, he was able to confirm some of the same testimonies. But did these healings make it into Time magazine? I don't follow Time, but I suspect not.
Delia Knox's healing, getting out of a wheelchair, did make it to at least one local news outlet because I saw the healing online. Not too long after the healing, I was able to find an old human interest news piece about her, the gospel singer in a wheelchair, and clips of her singing in a wheelchair before the healing.
But most healings do not make it onto secular news. It doesn't fit into the worldview of a lot of reporters and they would dismiss them as easily as they would dismiss following up on a UFO sighting. A lot of them also want to look professional, not like the one who brought the UFO story or the healing story to the newspaper.
Amie Semple McPherson was a colorful character. I wouldn't encourage people to imitate her marriage choices, but from what I have read, the newspaper people in San Diego treated what was going on there as real healings. i read an article about it, but haven't dug through the newspaper clipping myself. This was a little later, but you could look into that if you have great trust in the news media.
